Tephrosia capensis (Jacq.) Pers. var. acutifolia E.Mey., commonly known as the Cape fish poison or wild sweet pea, is a perennial herbaceous plant that belongs to the Fabaceae family. The plant is native to Southern Africa and can be found in various habitats such as grasslands, savannas, and rocky areas up to an altitude of 2800 m above sea level.
Appearance:
The plant typically grows up to a height of 60 cm and has a sprawling habit with a woody base. The stems are slender, and the leaves are pinnately compound, with 3-7 pairs of leaflets and a terminal leaflet. The leaflets are ovate and have a pale, bluish-green color. The flowers are purple or pink and are arranged in dense, axillary racemes that arise from the leaf axils. The fruits are cylindrical, hairy pods that contain brown seeds.
Uses:
The plant has a variety of medicinal uses. The roots, leaves, and stems contain compounds such as rotenoids, which have anti-cancer and anti-inflammatory properties. The plant has traditionally been used to treat wounds, fever, and infertility. It has also been used as a fish poison, where crushed leaves of the plant are thrown into the water to stun fish, making it easier for fishermen to catch them. However, the use of this method is now discouraged as it can harm other aquatic life and is not an environmentally-friendly practice.
Some indigenous tribes also use the plant in traditional rituals and ceremonies, where it is believed to have magical and spiritual qualities.

Cultivation Method for Tephrosia Capensis (Jacq.) Pers. Var. Acutifolia E.Mey.
Tephrosia capensis (Jacq.) Pers. var. acutifolia E.Mey. is a hardy perennial plant that is drought-resistant, and grows well in various soil types. When growing this plant, it is advisable to plant it in an area with full sun exposure and well-drained soil for optimal growth. The plant prefers a slightly acidic to neutral soil pH level of 5.5 to 7.5.
The planting should be done in the spring season after the last frost. Lightly dig the soil to a depth of about 8 inches, and add some organic manure or compost to improve soil fertility. Plant the seedlings at a spacing of 12 to 18 inches apart, depending on how big the mature plant will grow.
Watering Needs for Tephrosia Capensis (Jacq.) Pers. Var. Acutifolia E.Mey.
When caring for Tephrosia capensis (Jacq.) Pers. var. acutifolia E.Mey., it is important to ensure the plant receives adequate water. The plant grows well in dry soil, and it does not require regular watering. However, when planting it, water the seedlings moderately to help them establish deeper root systems.
After that, it is advisable to water the plant sparingly, about once every two weeks, unless there is a prolonged drought. Overwatering this plant can lead to root rot and other fungal diseases.
Fertilization for Tephrosia Capensis (Jacq.) Pers. Var. Acutifolia E.Mey.
While Tephrosia capensis (Jacq.) Pers. var. acutifolia E.Mey. is a hardy plant, it still requires some level of fertilization to maintain optimal growth. During the planting process, mix some slow-release fertilizer into the soil, or add some organic manure or compost to the soil to boost soil nutrients.
Thereafter, apply a balanced liquid fertilizer once every two months, during the growing season. It is essential to avoid using nitrogen-rich fertilizer because it can lead to excessive foliage growth, which can negatively affect the number of flowers this plant produces.
Pruning for Tephrosia Capensis (Jacq.) Pers. Var. Acutifolia E.Mey.
Pruning Tephrosia capensis (Jacq.) Pers. var. acutifolia E.Mey. is not a requirement but can be beneficial to the plant. It is recommended to trim the plant after the blooming season to help maintain its compact growth habit.
When pruning this plant, use sterile pruning tools, and remove any damaged or dead plant parts. Cutting back the plant will encourage new growth, which leads to a more robust plant.
Propagation of Tephrosia capensis (Jacq.) Pers. var. acutifolia E.Mey.
Tephrosia capensis (Jacq.) Pers. var. acutifolia E.Mey., also known as Cape tephrosia, is a perennial shrub that is native to Southern Africa. The plant is commonly propagated through seeds or cuttings.
Propagation through seeds
The seeds of Tephrosia capensis can be collected from the ripe pods, which turn brown and split open when mature. The seeds should be sown in well-draining soil during the spring or early summer months. The seeds require a warm temperature of at least 20°C to germinate, and they should be covered lightly with soil.
Once the seedlings have emerged, they should be watered regularly and provided with plenty of light, preferably direct sunlight. When the seedlings have developed several leaves and are roughly 10 to 15cm tall, they can be transplanted into larger pots or containers. Alternatively, they can be planted directly into the ground in a suitable location.
Propagation through cuttings
The stem cuttings can also be used to propagate Tephrosia capensis. The cuttings should be taken during the spring or early summer months from new growth, and they should be roughly 10 to 15cm in length. The cuttings should be treated with rooting hormone and planted in well-draining soil. The soil should be kept moist, but not waterlogged.
The cuttings should be placed in a warm location with indirect sunlight. After 3 to 4 weeks, the cuttings should have developed roots, and they can be transplanted into larger pots. To promote bushy growth, the tips of the main stems can be pinched off once the plant has reached the desired height.
Overall, Tephrosia capensis (Jacq.) Pers. var. acutifolia E.Mey. is an easy-to-grow plant that can be propagated through seeds or cuttings. By following these propagation methods, gardeners can ensure that they have a steady supply of this attractive shrub.
Disease and Pest Management for Tephrosia capensis (Jacq.) Pers. var. acutifolia E.Mey.
Tephrosia capensis (Jacq.) Pers. var. acutifolia E.Mey., commonly known as Cape beach-pea, is a beautiful plant that requires proper care to thrive. Like any other plant, it is susceptible to pests and diseases that can cause significant damage. It is crucial to identify the common pests and diseases that might affect Tephrosia capensis (Jacq.) Pers. var. acutifolia E.Mey. and know how to manage them effectively.
Common Pests
Aphids: Aphids are tiny insects that feed on the sap of the plant, causing stunted growth and distorted leaves. They also excrete honeydew, which attracts ants and promotes the growth of black sooty molds. To manage an aphid infestation, you can spray insecticidal soap on the plant or introduce natural predators such as ladybugs and lacewings.
Spider Mites: Spider mites are small pests that spin webs on the undersides of leaves and suck the plant's sap, causing leaves to turn yellow or brown. To manage a spider mite infestation, you can spray the plant with water to knock the pests off or use insecticidal soap. You can also introduce natural predators such as predatory mites.
Caterpillars: Caterpillars are the larvae of moths and butterflies that feed on the leaves of the plant, causing large holes and skeletonization. To manage a caterpillar infestation, you can pick them off by hand or use Bacillus thuringiensis (BT) spray.
Common Diseases
Root Rot: Root rot is caused by waterlogged soil, leading to the plant's root system's decay and death. To manage root rot, ensure that the plant is grown in well-draining soil and that the plant's roots are not left to sit in water.
Fungal Leaf Spot: This disease is characterized by brown or black spots on the leaves, which can cause defoliation. To manage fungal leaf spot, pick off infected leaves and dispose of them to prevent the disease from spreading. You can also use a fungicide to treat severe cases of fungal leaf spot.
Virus Infections: Virus infections can cause various symptoms, including stunted growth, leaf discoloration, and leaf distortion. Sadly, there are no proven treatments available for virus-infected plants. Therefore, it is crucial to remove and dispose of virus-infected plants to prevent the spread of the disease to healthy plants.
With proper care and management, Tephrosia capensis (Jacq.) Pers. var. acutifolia E.Mey. can thrive and provide a beautiful addition to any garden. Regular monitoring and early detection of pests and diseases can help prevent significant damage to the plant and ensure healthy growth.
